Pinout
| Pin | Name | Description |
|---|---|---|
| 1 | VCC | 5V power supply |
| 2 | GND | Ground |
| 3 | IN1 | Control signal for Relay 1 |
| 4 | IN2 | Control signal for Relay 2 |
Working Principle
Each relay operates using a control signal (3.3V-5V). When a signal is sent to the input pin (e.g., IN1), the corresponding relay activates, closing the Normally Open (NO) circuit and powering the connected load. The module uses optocouplers to isolate the control circuit from the high-power circuit, ensuring safety and protecting the microcontroller.
Relay Terminals
- **COM**: Common terminal
- **NO (Normally Open)**: Connects to COM when the relay is active
- **NC (Normally Closed)**: Connects to COM when the relay is inactive
Applications
- Home automation
- Industrial equipment control
- IoT-based projects
- Robotics
- Smart irrigation systems
